The 43-year-old from San Antonio took to Twitter Thursday to announce that Election Day 2020 will see the culmination of three years’ work “building most powerful campaign ever seen in politics.”

By Election Day 2020 we will have spent nearly three years building the most powerful campaign ever seen in politics. We will have the ability to contact directly with nearly every @realDonaldTrump voter in some method. https://t.co/mhheiNFLcb

Parscale’s tweet linked to an op-ed published Thursday in The Hill by Tara McGowan, founder of a progressive organization helping Democrats’ election efforts.

McGowan admitted that what Trump’s 2020 campaign has already built to reach and mobilize voters “terrifies” her, noting how the explosion of “social media and mobile apps have transformed how we live our lives and how political elections are won or lost.”

“Donald Trump’s campaign has taken advantage of these changes to build a highly strategic reelection campaign that any potential 2020 candidate should pay attention to,” McGowan added, noting some examples.

She suggested Trump “is utilizing a modern playbook to win” by focusing on digital platforms to reach voters, and warned that “Democrats are entering the 2020 race at a disadvantage.” She suggested Democrats should “center their campaigns around digital talent and strategies” in order to compete with Republicans who, with Parscale’s expertise, are successfully prioritizing digital platforms.
